`open()` exception

Need to check for a valid scanner (filepath) in

JLS/src/jls/JLSStart.java

Line 1131 in c27b54d

Scanner input = getScannerForFile(filePath);

(Points after this assume the scanner is non-Null).

Check conditions that can cause the scanner to be null (file moved or renamed or path changed while running maybe?)

Is it possible this is related to #10? I made #11 a bit ago which adds a null check on the line you mentioned, in addition to other spots with the same problem.

@AmityWilder Yes, it's the same issue. Closing this issue since it's both redundant and pr#11 should resolve. (I probably won't be able to accept PRs this week. I hope to have time for review the week of the 23rd). Thanks!
